[WEIRD] working kernel off RH7's gcc-2.96!?

[WEIRD] working kernel off RH7's gcc-2.96!?

[rml]

i dont want to revisit the flame fest (at all, please) but it seems i have been
using a kernel that successfully compiled under RedHat 7's gcc snapshot (2.96). 
i normally use gcc-2.91.66 for everything (mv kgcc gcc) but just synced my
system with rawhide, so the gcc/kgcc pair is back on my system and i forgot. so
i recompiled to test11 yesterday, and:

[00:05:51]rml@phantasy:~# cat /proc/version 
Linux version 2.4.0-test11 (rml@phantasy) (gcc version 2.96 20000731 (Red Hat
Linux 7.0)) #1 Mon Nov 20 19:06:06 EST 2000

the odd thing is, not only did it compile, but my machine has been up for a day
with heavy use in X with a full-featured kernel! not only no OOPSs, but no bugs!

the only thing i thought of was that alan's kgcc detection routine was in-place,
and using the detected kgcc to compile but then doing a hardcoded use of "gcc"
to grab the version ... but i could not find the code by grepping.

so i went ahead and removed kgcc from my path and recompiled, and sure enough --
it compiled fine.

just fyi, but someone tell me i am on crack... regardless, i am about to reboot
into a gcc-2.91.66 kernel.

Just keep in mind that 'seems to run fine' doesn't clearly show cases
like something in the signal handling code got miscompiled for a
special case or a bit error in the file system code. You could be
lucky, it might also show itself as more frequent crashes later etc.
